ʻO ka pūnana kahi fossa liʻiliʻi.
ʻElua mau hua i loko o kahi paʻa, i kekahi manawa nalowale paha ka paʻa mua ma muli o ka predation. Ma mua o 20% o nā moa e ola, ʻoiai ke kiʻekiʻe o ke ola makua. Haʻalele nā manu ʻōpio i ka pūnana a hoʻopuehu a puni ka mokupuni, e hana ana i nā pūʻā liʻiliʻi.
ʻO Plover heluna kanaka o Saint Helena
ʻO ka helu o nā plovers o Saint Helena i koho ʻia ma 200-220 oʻo oʻo. Eia nō naʻe, hōʻike ʻia nā ʻikepili hou i hōʻiliʻili ʻia ma 2008, 2010 a me 2015 e ʻoi aku ke kiʻekiʻe o ka nui o nā manu laha a mai nā 373 a ʻoi aku ma mua o 400 mau mākua makua.
Hōʻike kēia ʻikepili aia he loaʻa hou ʻana i nā helu. ʻAʻole maopopo ke kumu o kēia ʻano fluctuations. Akā ʻo ka emi nui o ka heluna kanaka e 20-29% e hana mau nei no nā makahiki he 16 i hala a i ʻole ʻekolu mau hanauna.

Ke noʻonoʻo nei i ka hoʻonui ʻana o ke kaomi anthropogenic ma muli o ke kūkulu ʻia ʻana o ke kahua mokulele, pono e hōʻemi hou ʻia ka nui o nā manu manuahi.
ʻO ka makaʻu nui i ka laha e hōʻike ʻia e nā pōpoki, nā ʻiole e ʻai i nā moa a me nā hua manu.
Hoʻonohonoho ʻia ʻo zuek o Saint Helena me he mea lā hoʻoweliweli.
Ke hoʻomaka nei nā papahana e kāohi i nā helu manu a hoʻāʻo e kāohi i ka emi.
Nā kumu no ka emi ʻana o ka helu o nā plovers Saint Helena
ʻO ka plover Saint Helena wale nō ka mea ola ʻāina endemaka ola i loaʻa ma Saint Helena (UK). Ua lilo ka hanai holoholona holoholona i mea pono ʻole ma luna o ka hapa nui o ka wahi, kahi i alakaʻi ai i nā loli nui i ka herbage. ʻO ka ulu ʻana o Sod ma muli o ka hoʻemi ʻia o ka hānai holoholona o nā holoholona (hipa a me nā kao) a me ka hōʻemi ʻana o ka ʻāina mahi hiki ke alakaʻi i kahi hōʻemi o ka maikaʻi o ka hānai ʻana a me ka pūnana ʻana i kekahi mau wahi.
ʻO Predation ke kumu nui o ka hōʻole ʻana o nā manu i ka pūnana. Ke hoʻohana nei i nā mea ʻike no ka ʻimi ʻana i ka neʻe ʻana o nā holoholona a me nā kāmele infrared, ua ʻike ka poʻe loea i nā pūnana i hoʻopōʻino ʻia e nā mea hōkai, aia ka helu o ke ola o nā keiki mai ka 6 a 47%.
ʻO ka hoʻonui ʻia o ka hana leʻaleʻa o ka lawe ʻana i nā wahi semi-wao akua hiki ke alakaʻi i ka luku a me ka luku ʻia ʻana o nā pūnana.
Ke lawe nei nā kūkulu hale i nā hailona hou. Nui ka maopopo ʻole e pili ana i nā puke kalepa a me ka hoʻonui ʻana o ka poʻe mākaʻikaʻi i manaʻo ʻia. Paipai ke kahua mokulele kūkulu i ke kūkulu ʻana i nā hale hou, nā alanui, nā hōkele a me nā papa kolepa, e hoʻonui ana i ka hopena maikaʻi ʻole i nā ʻano manu manuahi. No laila, ke hoʻomaka nei ka hana e hana i nā kahua pūnana kūpono i nā wahi pā maloʻo, manaʻo ʻia ʻo ka hoʻokō ʻana o kēia papahana e alakaʻi i ka hoʻonui ʻana i ka nui o nā plovers.
Nā hana mālama plover a Saint Helena
Ua pale ʻia nā ʻano manu āpau ma Saint Helena e ke kānāwai mai ka 1894. Aia kahi National Trust (SHNT) ma Saint Helena, ka mea i hoʻonohonoho i nā hana o nā hui kaiaulu lehulehu, alakaʻi i ka nānā ʻana a me ka noiʻi kaiapuni, hoʻihoʻi i nā wahi noho a hana pū me ka lehulehu. Ma kahi o 150 hectares o nā wahi hānai i hoʻokaʻawale ʻia no ka ʻanoʻano. Lawe ʻia ka hopu ʻana i nā pōpoki feral e alualu i nā plovers.
Ke hana nei ka Royal Society for the Protection of Birds, Agriculture and Natural Resources Department a me SHNT i kahi papahana e hōʻemi i ka hopena anthropogenic i ka plover Saint Helena. ʻO ka papa hana, i hoʻokō ʻia mai Ianuali 2008, i hoʻolālā ʻia no nā makahiki he ʻumi a me nā ana e hoʻonui ai i ka nui o nā plovers a hana i nā kūlana paʻa no ka hana hou manu.
I ke kula puka puka ma ke Kulanui o Bath, ke hana nei nā biologists e pale aku i nā mea hōkai mai ka ʻai ʻana i nā hua manu plover.
Ua hōʻike ʻia nā hopena o kēia mau hoʻāʻo ʻana ʻaʻole make ka nui o nā hua i ka pūnana a me nā moa mai nā mea ʻaihue, akā ma muli o nā kūlana maikaʻi ʻole o ke kaiapuni. ʻIke ʻia kekahi make nui ma waena o nā manu makua. ʻO nā hana mālama no ka Saint Helena plover me ka nānā mau ʻana i ka nui.
Mālama i nā wahi hānai a me ka nānā ʻana i nā ʻano holoholona i hoʻolauna ʻia. Ke nānā nei i nā loli i ka nohona. Kaohi ʻana i ke komo ʻana i nā wahi semi-wao nahele kahi e noho ai nā ʻano laha ʻole. Hāʻawi i nā hana hoʻoliʻiliʻi no ke kūkulu ʻana i kahi kahua mokulele i ka pāpū. E nānā i nā pōpoki hānai a me nā ʻiole a puni nā pūnaewele hoʻopaʻa manu. E nānā pono i ka hoʻomohala ʻana o ke kahua mokulele a me nā pono mākaʻikaʻi e hiki ai ke hōʻino i ka wahi o ka plover o Saint Helena.
